Hello, I’d like to differently color some gyri (eg, insula, so as to be better able to see it in contrast to nearby superior temporal gyrus); how can I do that?
(And then of course, be able to save that without losing the ability to retrieve the original colorization.)

Thank you.

You can choose the colors of individual ROIs by using the label tool.
http://brainsuite.org/delineation/roi/label-painter-tool/

You can modify the colors, recolor and save the surfaces.
If you want back the original color, you can click on load description, select the label description xml file in the atlas directory and then goto surface view and select color by labels.

Thank you Anand, I’ll give it a try! And if I change some, could I cause an xml file with those changes to be saved, so I could easily alternate between different coloration schemes?

Ok, I selected ‘View’, ‘Delineation Tool Sidebar’, selected ‘L.Insula (wm)’ at ‘description’, & changed its color as it showed in the Sidebar color selector box (but the color did not change on the brain itself).

Then I clicked ‘Save Desc.’, & entered a new filename.

Then I looked in ‘File’, ‘Open’, ‘Label Volume’, but did not find the file I thought I had created in the C:\Program Files\BrainSuite18a\svreg\BCI-DNI_brain_atlas folder. Then I closed BS, & looked directly in the above folder, and it wasn’t there. Reopened BS, looked in ‘Open’, ‘Label Volume’, & only found the main brain label file, not the one I tried to create.

Not sure what I’m doing wrong.

You are not creating new labels, just the new color scheme, right?
You can load the original volume, then open label. this will show labels in the original color scheme.
to load your new colorscheme, open label toolbox, load description and load the xml file that you saved. this should show the changed colors.

[DanM]

Yes, just a new color scheme. Problem is I don’t see my saved description file anywhere. I first just saved a named file, and after nothing showed up, made sure to add .xml after the file name (I’d first presumed that the extent would be auto-added), but still can’t find the file(s) I’ve been trying to save anywhere. Is there any other button I should click in the label toolbox?

Oh, and I’ve tried to look for any file with today’s date, no luck.

Not sure why that would happen. Please make sure that you are saving the xml file in the directory where you have write access. Perhaps you tried to save it in a read only directory, like BrainSuite installation directory?

[DanM]

Aha! Trying to save the .xml file in BrainSuite installation directory is exactly what I have been doing! It never occurred to me that I wasn’t supposed to, though it makes perfect sense that it could often/always be a no-no! Thank you so much!
